STACY B.`HASELTNE, 0F CHICAGO, LLNOIS., ASSIGNOR T0 W. H. MNER, INC., 0F CHICAGO, ILINOIS, A. CORPORATION OF JlELUAB/E can consfrianorron Application led April 27,

This invention relates to improvements in car construction, 4 and more particularly means for preventing the separationy of body and truck holsters of passenger cars.

@ne object or' my invention is to provide a combined locking and centerV pin arrangement for car holsters which will he of substantial construction throughout and presenting a large cross sectional area to minimizethe possibility of shearing on or oi breaking under tension strains when the car is in collision, to thereby maintain the connection between the trucks and body and thus prevent telescoping.

' Another object of my invention is to provide a one-piece, combined locking center pin ci' substantial cross section throughout its lene'th, and which may be readily inserted and removed when desired, and, when in position, is held against turning with respect to one of the holsters.

Another and more specilic object of my invention is to provide arrangement of the character indicated, wherein adjustments may be made by means of shims or equivalents, to take up for wear on the center bearing plates so as to always maintain the eiliciency of the connection between the holsters.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming a part of this specilication, Figure 1 is a top planview o portions of body and truck holsters of a passenger car, showing my improvements in con'- nectionv therewith, parts being broken away as unessential to the disclosure. Figure 2 is an enlarged, vertical, sectional view, corresponding to the line 2-2 0I" Figure 1. Figure 3 is a vertical, sectional view at right vangles to Figure 2 and corresponding to the line 3-3 of Figure .2. Figure 4 is a horizontal, sectional view, corresponding to the line 4 4: of Figure 2. Figure 5 is a detailed perspective of the lockingrplate used with my improvements. Figure 6 isa view similar to Figure` 2, illustrating another embodiment or my invention.v Figure 7 is a view similar to Figure 3, illustratinga `still Jrurther embodiment of the invention. AAnd Figure 8 isa ieee. serial No. 273,185.

horizontal, sectional view of the form illustrated in Figure 7 and corresponding to .the line S-S thereof.

In said drawings', and'referring iirst tothe construction illustrated in Figures 1 Vto 5, inclusive, 10 indicates generally the body bolster of the car, 11 the truck bolster, 12 the combined locking and center pin, and 13 the locking plate associated with the pin. .l

The body bolster 10 may be of any suitable or desirable construction and is provided with a tubular center or king pin section lil which merges into a rectangularpoclret 15 at'the upper end and into a truncated conical recess 16 at the lower end. y

The center pin section` 14 is adeitionally provided with diametrically opposed, vertically extending grooves 17, each of which approximates 900 in extent, with radially disposed end walls 18-18, as best indicated in Figure Il. With 'the formation described, it is evident that horizontal, diametrically disposed, upwardly facing shoulders 19-19 are formed at the bottom of the rectangular pocket 15, said shoulders 19 corresponding approximately to the shape of the groove 17 but offset 900 with respect to the latter. rlhe body bolster 10 is alsoshown formed with an integral center bearing plate section 2O which cooperates with a corresponding truck cen- `ter bearing plate 21, suitably securedto the clearly shown in Figures 2 and 3. l

The pin 12 has a cylindrical shanlr of the samecross section throughout its length and is provided at its lower end with an annular iiange 25 constituting a head which is positioned beneath the partition 26 and is adapted to engage with the under-face of the latter upon upward movement. or" the pin'when the body andtruclrbolsters separate, Freferably, the clearance allowed between the flange-or.

lhead 25 and the partition 26 will he less than` ythe depth ofthe male flange 80 of the center bearing plate 21, so that the center bearing 2o Y n of the center pm openings and, when the der-stood, the

plates cannot become disassembled unless there is failure of the pin 12.

The pin 12 may be cored, as indicated at '27, to lessen the weight and amount ofmaterial required and facilitate its manufacture, the ycaring being kept reduced sui'- liciently as; not to materially affect the strengthvalue of the pin. v l Atits upper end, the pin 12 is shown pro-I vided with diametrically opposed, laterally extending, heavy, thick flanges 28-28 offan outline corresponding to the grooves 17 and just sufficiently smaller than the grooves as' to permit passage ofL the head flanges 28 longitudinally therethrough. *As will be unpin 12 is inserted from the bottom'with tne lateral flanges 28 aligned with the longitudinally extending grooves flanges 28 are above the shoulders 19 and the' shims 29, `when any of the latter are used, the pin 1s then given a 90 turn, so as to bring the flanges 28 above the shoulders 19.

Theshims 29,@which may be of any desired Vnumber or which may be omitted Ventirely if desired, are of like construction and each preferably extends through an arc of approxiinately'90o, as shown in Figure 1, 'and has an inner curved edge 30, radially extending edges 31', squared ends 32, and a straight Y outer face 33,'so that, when the shims are in place, they substantially cover the shoulders 19'while leaving two arcuate spaces for the passage of-the pin flanges 28 before the n latter are turned and rested upon the shiins.

' ing armsor flanges 35--35.

flanges is provided on its inner side with a circular face 36 of approximately the sameY radius as thatof the surface of the pin 12,

l Vthe flanges 35 having substantially radially disposed, diverging edges V37-37.l .Each flange 35,at the upper portion thereof, has a'flat outer surface l38 extending approxi- 'matelyV half the length of the flange, and the surface is then rounded, as indicated'at 39,

thusvproviding downwardly facing shoulders v 407-40 and above Vwhich are other downwardf ly facing shoulders 41-41- The lower sections of the flanges 35 having the inner and outer cylindrical faces 36 and Y fee in Figure l, andvhence the plate 13 will be 39-areadapted to extendinto the offset grooves 17 of the body bolster,` as indicated thereby prevented' from turning. The depending flanges35 are obviously designed to' straddle the upper end of the Vpin 12 and Y Vpass' between the Y laterally extending head or flange sections 28 thereof, thereby preventing the pin 12 fromturning with reference tothe body bolster when the locking plate 13 is in position. The portions of the flanges f ynecked-in or reduced sections, thereby presenting great strength againstany tendency to shear the same and Valso against tension when thebolsters tend to separate. Further, while the pin is heldV against rotation with respect to the body bolster, nevertheless, the

truck bolster is free to turn with respect to the'pin; Should wear'occurvon the center bearing `faces, 1t is evident that more or less of the shims may be used to compensate therefor and to leave the desired'clearanceV between the lower head'25 of the pin and the opposed bearing shoulder sections of the4 truck bolster, to thus limit the permissible` vertical play of the pin to the desired amount' at all times.

Referring next to the construction illusytrated in Figure 6, the body bolster isV indicated at 110, the truck bolster at 111, the improved pinat 112,.and the locking plate` at 113. I

The body bolster is provided With a king pin or center pin section 114: of the same cross sectional contour as the section V14 of the lirst described form', the center pin section, however, in the modification of F igure 6, being downwardly flared,vas indicated at 50, and thence terminating in a truevcylindrical section 51. The rectangular opening 115 at the upper end, the locking plate 113, the shims 129, and the formation of the upper end of the pin 112 are the same as in the form first described. t

-The truck bolster 111 is recessed onits upper face, as indicated at 52,'toV receive a depending ange53 of the `truck center bear ing platel121. The latter-cooperates with the body bolster center bearing plater section 120,. but in this modification no male and fe-` male formations of thev center bearing plates eo v,

los

iseniployed. Furthermore, the opening123 in truck Center plate 121 and the opening 12e 'in the horizontal partit-ion of the truck bolster are truly circular throughout, but of larger diameter than the upper shank portion 53 of the pinf112, and of sullciently large diof the upper headedV end of the pin.

f In this modification, the pin ,112v has the lower portion of the shank of an enlarged diameter, as indicated at 54,` the latter sectionv being merged with`V` the upper main section ameter to permit the passage therethrough Y n 53 b5, a truncated conical section 55",V the latter l conforming to the correspondingtruncated Y' conical section y5() ofl the" body bolster.. The

pin 112 has an annular flange or head 125 at its lower end, adaptedfto be limited in its upward movement by the partition 126 of the truck bolster. The pin may be cored, as in-Y dicated at 127. 4

In this modification,- the pin is inserted upwardly through the openings 124 and 123, and the lateral flanges at the top of the pin, while the latter is in one position, are passed up through the opening in the body bolsterl and given a quarter turn and the locking plate applied, as will be understood.

It will be observed that a larger cross sec-l 212, and the locking plate at 213. In'thisv modification, the pin 212, the locking plate 213, and the body bolster are the same as the corresponding parts of the first described modification, and detailed description of these parts is deemed unnecessary.

The truck cent-er bearing plate 221 is similar to the center bearing plate 121, in that it has a depending liange 63 seated within a recess of the truck bolster, and similar to the bearing plate 21 in that it has two diametrically disposed, upstanding male flange sec-- tions 280 positioned within the female recess 216. yThe plate 221 has the central passage 64 thereof of the same cross section and contour as the opening 22 of the plate 21 first described, and, similarly, the opening 65 in the partition 226 of the truck bolster corregrooves 0r recesses in the partition 226l and' Y center bearing plate 221.

The flanges 71 are of such a length thatV the upper ends thereof project into the female recess 216 of the body bolster and .are

positioned :between the male flange sections 280 of the truck bolster center plate 221. At the lower ends, each of the members is formed with a laterally offset arcuate' flange4 72 embracing the head 225 of the pin, said flanges 72 preferably being extended circumferentially,as indicated at 7 35-7 3 in Figure 8, beyond the edges of the upstanding flanges 71 so that each flange 72-73 is of approximately 18(4)O in extent. In this manner, the

vent turning of the annularhead or flange 225 of the pin is pro-l vided with substantially a 360o shoulder bearing on the under sides of the members 70, and the flanges 7 2--73 ofthe latter in turn have a substantially 360O shoulder `bearing against the under side of the partition226.

In assembling` the construction shown in Figures 7 and .8, the pin is entered the same as the pin 12 of the first described form, and

when the pin 212 is partially inserted'the members-70 are applied thereto andentered through the recesses provided therefor, it being evident that the pin 212 may'be'given a quarter turn within the member'sf'O, as well as within the center pin sectionlof the body bolster.

Considering the combined locking centerv pin of Figure 7 as comprised of the pin proper 212 and the members 7 0,A it is evident Vthat a larger cross sectional area is providedv yto resist Ishear in the meeting plane of the center bearing Vplates than in the case of thev construction shown in the first modification. l When I yhave herein shown and described what I consider the preferredmanner-of car-- rying out my invention, the sameis merely l illustrative and I contemplate all changes' and modifications which come withinj` the scope of the claimsV appended hereto: v
